connect_slots_by_name_UI_demo.py

"""
Example showing how to use auto-connecting Python methods/functions to
matching widgets with the `QMetaObject.connectSlotsByName` call thats compiled
into the python-Ui code.

The code generator always gives Qt object names! No need to care about that.
This way you merely need to make your methods fit like:
* make them slots via `@QtCore.Slot()`
* name them like `on _ Qt-object-name _ Signal-name`
